Abstract Nickel is a heavy metal distributed ubiquitously in nature. It accumulates in soil as a result of human activities, including mining and industries development. It may be poisonous to plants, humans, animals and microorganisms. The present study was implemented as a factorial experiment with a Randomized Complete Block Design (RCBD), of three replications in calcareous soils of Karaj...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
in 2007, an experiment was conducted at the farm of the college of agriculture, isfahan university of technology, in najaf abad (lavark), to study the effects of two pre-emergence herbicides (trifluralin and ethalfluralin) when combined with the three post-emergence herbicides setoxydim, cycloxydim and haloxyfop and the two post-emergence herbicides desmedipham and phenmedipham on weeds and the...
in order to investigating the effects of planting date and harvest time on the quality performance of pear millet, an experiment was conducted in agriculture research station of gorgan in a randomized complete block design with four replications and factorial arrangement. this experiment included five planting dates (may 5th, may 25th, june 14th ,july 4th, july 24th) and three harvest times (90...
In order to investigate the effects of water deficit stress on grain yield and some traits three sunflower cultivars, have been used based on randomized complete block design using a split plot experiment at Agricultural Research Station of Azad University of Tabriz in 2007. Five levels of water deficit (50, 100, 150, 200 and 250 mm evaporation from evaporation pan, class A) were assigned as m...
the study was designed to evaluate the impact of rhizobium bacteria and mycorrhizal fungi and iron sulfate was performed on chickpea plants. treatments rhizobium bacteria (inoculated and non-inoculated), mycorrhizal fungi (glomus mosseae, glomus intraradices and non-inoculated) and various amounts of iron sulfate fertilizer (0, 40 and 80 kg per hectare) with a factorial experiment in a randomiz...
In the present study, twenty two selected lines from eleven Iranian eggplant (Solanum melongena L.) landraces along with Varamin landrace, as control, were studied in a randomized complete block design with three replications in three locations (Karaj, Varamin and Dezful). Sum of yield and marketing score for each line was recorded. Analysis of variance for yield showed significant differences ...
augment of germination rate is important in seedling establishment and crop yield. a set of study in laboratory & field conditions at agronomy department of university of tehran was conducted during 2004-2005. in lab. experiment the effects of seed priming was evaluated on germination indices (germination percentage and rate) of chickpea genotypes in a factorial experiment of 4×3×2 arranged in ...
field experiment was conducted to assess the efficacy of wheat residues and different densities of sunflower in weed control during 2007 growing season. the experimental design was a randomized complete block with three replications. the experiment was set up in factorial arrangement, amount of 0, 1250, 2500, 3750, 5000 kg ha-1 of wheat residue and burning of residue (5000 kg ha-1) were the lev...
in order to evaluate the effects of nitrogen fertilizer on yield, yield components and dry matter remobilization of different rice genotypes, a field experiment was carried out at the farm of ramin agricultural and natural resources university (ahwaz/iran) during 2007. experiment was arranged in a split plot based on randomized complete block design with three replications. four nitrogen fertil...
